We present an efficient algorithm to determine the maximal class of confluent τ-transitions in a labelled transition system. Confluent τ-transitions are inert with respect to branching bisimulation. This allows to use τ-priorisation, which means that in a state with a confluent outgoing τ-transition all other transitions can be removed, maintaining branching bisimulation. In combination with the removal of τ-loops, and the compression of τ-sequences this yields an efficient algorithm to reduce the size of large state spaces.
